I want to get a PCATD (that's PC Aviation Training Device) for IFR training. A new Elite is 4K and a new ASA/On Top is 2.7K. They both are FAA approved to do the same thing and seem to be comparable units. I've never flown either one and wonder if any of you guys have or if you have an opinion on which one is better. I'll go with the ASA unit unless someone can convince me the Elite is worth the extra cash.
